PyQt5 QSpinBox – 获取相交区域

在本文中，我们将看到如何获得旋转框的子区域与给定矩形或区域之间的相交区域，子区域包含旋转框的子区域所占据的组合区域。为了获得子区域，我们使用childrenRegion方法。下面是相交区域的样子。

In order to do this we use the intersected method with the children region object of the spin box

Syntax : children_region.intersected(rectangle)

Argument : It takes QRect object as argument also it can take QRegion object

Return : It returns QRegion object

下面是实现

# importing libraries
from PyQt5.QtWidgets import * 
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import * 
from PyQt5.QtCore import * 
import sys
  
  
class Window(QMainWindow):
  
    def __init__(self):
        super().__init__()
  
        # setting title
        self.setWindowTitle("Python ")
  
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
  
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
  
        # setting range to the spin box
        self.spin.setRange(0, 999999)
  
        # setting prefix to spin
        self.spin.setPrefix("Prefix ")
  
        # setting suffix to spin
        self.spin.setSuffix(" Suffix")
  
        # getting the children region
        children_region = self.spin.childrenRegion()
  
        # creating a label
        label = QLabel(self)
        label.setWordWrap(True)
  
        # setting geometry to the label
        label.setGeometry(100, 200, 200, 60)
  
        # QRect
        rectangle = QRect(100, 100, 20, 30)
  
        # getting intersected region between the Qrect and children region
        intersection_region = children_region.intersected(rectangle)
  
        # setting text to the label
        label.setText("Intersected region : " + str(intersection_region))
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())

输出 ：
